Program Plan Intro
Distance converter
Program plan:
Design the form:
- • Place a one text boxes control on the form, and change its name and properties to get the distance from the user.
- • Place a three label boxes control on the form, and change its name and properties.
- • Place a two group boxes control on the form, and change its name and properties.
- • Place a two list boxes control on the form, and change its name and properties to list of items.
- • Place a command button on the form, and change its name and properties to convert distance and then display it.
- • Place a command button on the form, and change its name and properties to end the application.
In code window, write the code:
Program.cs:
- • Include the required libraries.
- • Define the namespace “DistanceConverter”.
- ○ Define a class “Program”.
- ■ Define a constructor for the class.
- ■ Define required functions to run “Form1”.
- ○ Define a class “Program”.

- ■ Declare the required variables.
- ■ Check whether selected index for From list and To list is not equal to “-1”. If yes, display the result.
- ■ Otherwise, check whether From list is equal to “Yards” and To list is equal to “Feet”. If yes, calculate the distance in feet and display the result.
- ■ Otherwise, check whether From list is equal to “Feet” and To list is equal to “Yards”. If yes, calculate the distance in yards and display the result.
- ■ Otherwise, check whether From list is equal to “Yards” and To list is equal to “Inches”. If yes, calculate the distance in inches and display the result.
- ■ Otherwise, check whether From list is equal to “Inches” and To list is equal to “Yards”. If yes, calculate the distance in yards and display the result.

This is for Visual Basic I and is not in a textbook.
Create a Windows Form application. Use the following names for the project and solution, respectively: NFL Teams Project and NFL Teams Solution. Add any 6 NFL teams to a list box. When the user clicks a team in the list box, the list box’s SelectedIndexChanged procedure should display the State that the NFL Team is from in a label control. Example "Altanta Falcons" display Georgia, in the label. Look back at Chapter 5 for examples of list boxes.
I need some help understanding it. My teacher gave this to me as a example question.
Dice Simulator Create an application that simulates rolling a pair of dice. When the user clicks a button, the application should generate two random numbers, each in the range of 1 through 6, to represent the value of the dice. Use PictureBox controls to display the dice. (In the Student Sample Programs, in the Chap05 folder, you will find six images named Die1.bmp, Die2.bmp, Die3.bmp, Die4.bmp, Die5.bmp, and Die6.bmp that you can use in the PictureBoxes.)
True or False Forms and most controls have a Preferences property that allows you to change the object’s background color.

- If you know a vehicle’s speed and the amount of time it has traveled, you can calculate the distance it has traveled as follows:Distance = Speed × TimeFor example, if a train travels 40 miles per hour for 3 hours, the distance traveled is 120 miles. Create an application with a form. The user enters a vehicle’s speed and the number of hours traveled into text boxes. When the user clicks the Calculate button, the application should use a loop to display in a list box the distance the vehicle has traveled for each hour of that time period.arrow_forwardListBoxes may be added by using the Properties window.arrow_forwardmake a payroll application that will have a group box titled Payroll Information.

- The application displays a shipping charge that is based on the total price entered by the user, as shown in Figure 4-64. Start the application and then test it by clicking the Display shipping button. Notice that the Shipping charge box contains $13, which is not correct. Now, test the application using the following total prices: 100, 501, 1500, 500.75, 30, 1000.33, and 2000. Here too, notice that the application does not always display the correct shipping charge. (More specifically, the shipping charge for two of the seven total prices is incorrect.) Open the Code Editor window and correct the errors in the code. Save the solution and then start and test the application.arrow_forwardDriver’s License Exam The local driver’s license office has asked you to create an application that grades the written portion of the driver’s license exam.

The following formula can be used to determine a moving object’s kinetic energy: KE =1/2mv2 In the formula KE is the kinetic energy, m is the object’s mass in kilograms, and v is the object’s velocity in meters per second. Create an application that allows the user to enter an object’s mass and velocity and then displays the object’s kinetic energy. The application should have a method named KineticEnergy that accepts an object’s mass (in kilograms) and velocity (in meters per second) as arguments. The method should return the amount of kinetic energy that the object has.arrow_forwardTuition Increase At one college the tuition for a full-time student is $6000 per semester.
